Albert Einstein – 14. 03. 1879. Was born German – Jewish physicist Albert Einstein, creator the theory of relativity, which apparently seems to be devoid of applications. However, it is a device which, without this theory would not work – a GPS receiver. In 1921. He won the Nobel Prize for his explanation of the photoelectric effect and contribution to the development of theoretical physics. From the age of four he played the violin. Elsa, his wife recalled:

As a little girl I fell in love Albert, because so beautifully played Mozart on the violin. […] „

Cartilaginous fish – Found fossils show that sharks living today belong to a group of cartilaginous fish. There are still very similar to their ancestors who existed 150 million years ago. According to experts, currently in the waters of the seas and oceans live 455 species of sharks. Joe Quattro professor of biology at the University of South Carolina. in 2006. he discovered species, which is very similar to the famous hammerhead sharks, but differs from it in terms of genetics.

DNA chain

DNA chainDNA chain

DNA chain – DNA strands looks like spiral ladders with the millions rungs, each of which carries the instructions written by chemical code. If we could unravel and stretch the DNA of a single human cell, measure the approx. 2 meters, its thickness, however, would amount to approx. 0.000002 mm. Chain DNA from the body of one man is 16 times longer than the path from Earth to the Moon.

DNA types

DNA types – Distinction is made between two types of DNA:

  • Nuclear DNA, in the nucleus of each cell of the human body consists of 20-25 thousand. genes. After the death of its host quickly degrades.
  • Mitochondrial DNA (mtDNA), contains only 37 genes. During the study, scientists use mtDNA, which is inherited only from the mother, it retains a relatively high resistance to the influence of sexual selection, however, it is a frequent mutations.
